Well how do you explain that my HDs work fine with hdparm -u1 but my
CD-ROM does *not*?

It's Mitsumi CR2801TE CD-R drive, and it corrupts silently data with
unmasked IRQs while reading -- I haven't had any writing problems.

Don't say it's unrelated to topic just because it happens to be CD not HD.

This is Pentium 120 with Triton chipset and MG motherboard.

(offtopic: this QNX demodisk is *cool*. Single floppy that runs the
realtime OS and has complete window system, web browser and web server
included, on the single 1.4MB floppy. Downloaded from qnx web site... i'd
hope Linux would be as efficient. I'm right now writing this message with
qnx loaded from the demodisk).
